摘要：

The complexing of Fe(II) with 2,4,6-tri(2'-pyridyl)1,3,5-triazine in the presence of Fe(III) represents a rapid alternative to the usual methods and provides good sensitivity. The results show that this method can also be used with very different Fe(II) or Fe(III) contents. The application described for the automatic determination of Fe(II) in ores and sinter with the continuous flow technique shows that this method can also be used in connection with automated systems. However, particular attention must be paid here to the fact that the working conditions have to be optimised for each matrix.
